摘要
逆变器满负荷时的电感电流有效值和电流峰值是滤波电感设计的两个重要参数。分析了双极性单相SPWM逆变器的输出电压特性及LC滤波电路的特性,提出了一种近似计算滤波电感电流有效值和电流峰值的方法。与仿真结果相比较,本近似计算方法具有较高的计算精度,为正确选择滤波电感提供了依据。
During full load running of inverter, the inductive current RMS value and the peak current are two important parameters for designing the inductor of the output LC filter. The output voltage characteristic of bipolar single - phase SPWM inverter and LC filter circuit characteristic were analyzed, one approximate calculation method was proposed ,comparing with the simulation result, it has higher calculating precision to provide basis for correctly selecting the inductor of the output LC filter.
